(i) Pre-Retirement (Aged 45-60)
Until now we have examined only those activities of our two subjects which have an impact on their GHG emissions at home and while travelling. However, as holders of senior posts at work, both Mr Prescott and Mr Bellamy now have responsibility for GHG sensitive decisions at work. With 70 employees, energy use and associated GHG emission at work is large. By replacing the 200 lights in his block of offices with energy efficient lighting and ensuring waste paper is recycled wherever possible, Mr Bellamy is able to cut GHG emissions by over 20 tonnes per year and save over £1400 in energy costs. These office based GHG savings are so large that they have been left out of the comparison figures to improve clarity.
At home our two subjects' children have moved out and their energy usage would normally drop back to the 'medium' energy use bracket. However, Mr Bellamys energy saving strategies around the house maintain the previous cuts in household energy related GHG emissions on costs. Similarly, his sourcing of locally grown food and recycling of household waste makes further reductions in individual GHG emissions.
Both Mr Prescott and Mr Bellamy continue to clock up around 18,000km in day to day travel each year. With no young children and more expendable income Mr Prescott decides to buy a Mercedes Benz S500, which leads to annual GHG emissions of nearly 7 tonnes at a fuel cost of over £1700. Mr Bellamy's chosen combination of public transport and bicycle continues to produce only 528 kg of GHG and cost only £380 each year.
For his annual holidays Mr Bellamy decides to stay in London and visit the various museums, galleries and shows the capital has to offer. By making use of his annual public transport pass he is able to travel around London for free, his 25 trips each summer producing only 7kg of GHG. Mr Prescott flies each year to Lima at a cost of £459, producing almost 3 tonnes of GHG on each round trip.
